Sailing is filled with intricacies of terms and techniques. The more knowledgeable I become of sailing, the more questions I seem to have. Wish I had found this book when I started sailing. Now, as a sailor of some experience, I find this book re-teaching me the basics in a way that answers more questions than it creates. Other books leave out explanation of terms and/or subjects and otherwise assume reader knowledge. This book covers sailing in a way that is thorough yet concise. The drawings and diagrams are extremely successful in deploying the author's subject. The information is complete without being textbook. It is enjoyable. If I had to rebuild my sailing library today, this would be the first but on the self!
